I recently discovered a roughed in bathroom in my house (it was a closet). It was hidden under the carpet and in walls and discovered when replacing sheetrock. This was not captured in the initial appraisal or inspection since it was hidden. If I wanted to turn this into a bathroom as originally planned, how do I go about this? Do I need to find someone to do permitted work so I don't have to worry about resale down the road? Can it be done DIY with no impact ? Not really sure where to go from here since it has been hidden since original build in the 50's judging by the plumbing. #home source
